CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority under 35 U.S.C. § 119 to U.S. Provisional Application Ser. No. 63/085,845, filed Sep. 30, 2020, the content of which is relied upon and incorporated herein by reference in its entirety.

BACKGROUND

The disclosure is directed to connector assemblies for telecommunication enclosures, and particularly connector assemblies, including adapters configured for positioning through ports of telecommunication enclosures.

Telecommunication cables are ubiquitous and used for distributing all manner of data across vast networks. The majority of cables are electrically conductive cables (typically copper), although the use of optical fiber cables is growing rapidly in telecommunication systems as larger and larger amounts of data are transmitted. Additionally, as data transmissions increase, the fiber optic network is being extended closer to the end user which can be premises, businesses, or private residences.

As telecommunication cables are routed across data networks, it is necessary to periodically open the cable so that one or more telecommunication lines therein may be spliced, allowing data to be distributed to other cables or “branches” of the telecommunication network. At each point where a telecommunication cable is opened, it is necessary to provide a telecommunication enclosure to protect the exposed interior of the cable. The cable branches may be further distributed until the network reaches individual homes, businesses, offices, and so on. These networks are often referred to as fiber to the X (FTTx) networks, which can include fiber to the premises (FTTp), fiber to the home (FTTh) and fiber to the antenna (FTTA) networks.

In an FTTH network, optical fiber is brought to the end user and connected to the optical network terminal (ONT) unit mounted on a wall at the end user. The ONT converts this optical signal into conventional electrical signals to provide voice (telephone), Internet (data) and video signals to the end user.

Fiber terminals are one type of telecommunication enclosure that is typically located near an end user in a FTTP network to distribute the final service to the end user. Typical fiber terminals are designed to drop services (to provide service connections) to a small number of premises having typically between four to twelve end users. The last service connection from the fiber terminal is made to the ONT, located at the end user using a drop cable. Typically, an optical connector attached to the terminal end of an optical fiber of the cable is preferred to allow quick, reliable field installation.

Given the rapid growth of telecommunication networks and the amount of data transmitted via telecommunication networks, there is a clear near for improved connections to telecommunications enclosures.

In an exemplary aspect, about 50 mm of the jacket 52 can be removed, leaving about 25 mm of stripped fiber. For example, a commercial fiber cleaver can be utilized to provide a flat or an angled cleave. No polishing of the fiber end is required, as a cleaved fiber can be optically coupled to the fiber stub in the splice device. The prepared end of the cable 50 is inserted through the rear end of the partially pre-assembled optical connection portion. When fully assembled, the connector assembly 100 can advantageously allow the length of the optical fiber cable to be adjusted in the field to avoid waste and the need to store excess length of unneeded cable.

FIG. 10 illustrates the securing of the exemplary connector assemblies 100, 200 into port structures 320 of a telecommunication enclosure when the optical connector is inserted through a port 330 of the enclosure. The combinations of the telecommunications enclosure with the connector assemblies 100, 200 can be used as components of a telecommunications network.
